Step-by-Step Instructions:

1. Position Hitch:

   • Hold the hitch up under the frame.
   • Position the holes in the brackets over the rivet heads at the rear of the frame.
   • Clamp the hitch in place to prevent movement.

2. Install Carriage Bolts:

   • Insert 1/2” carriage bolts with bolt plates through the holes in the frame beside the spring hangers.
   • Use 1/2” serrated washers, 1/2” lock washers, and 1/2” nuts to secure the bolts.
   • If access is limited due to gas tank placement, screw the bolt onto the pull wire and guide it through a more open area in the frame to the hole.

3. Drill Rear Holes:

   • Using the rear holes in the bracket as a guide, drill 5/8” holes into the bottom of the frame.
   • Install 5/8” bolts with 5/8” flat washers through the drilled holes and secure them with 5/8” flat washers, 5/8” lock washers, and 5/8” nuts.

4. Tighten Fasteners:

   • Torque 1/2” nuts to 70 lb-ft.
   • Torque 5/8” nuts to 115 lb-ft.

Torque Specifications:

• 1/2” nuts: 70 lb-ft
• 5/8” nuts: 115 lb-ft

Hardware List:

• (4) 1/2” Carriage Bolts

Installation Instructions for Trailer Light Wiring Kit

Part Number:

• 20252

Tools Required:

• Hot Air Gun or Appropriate Heat Source
• Wire Crimpers
• Drill (3/32” Drill Bit)
• Phillips Head Screwdriver
• Circuit Tester

Step-by-Step Instructions:

Step 1: Locate the Taillight Wiring Harness

1. Access the vehicle's taillight wiring harness.
2. Using the provided instructions, identify the appropriate wires for connection:
   • Green Wire: Right Turn & Stop
   • Yellow Wire: Left Turn & Stop
   • Brown Wire: Taillights
   • White Wire: Ground

Step 2: Make the Electrical Connections

1. Match the color-coded wires from the wiring kit to the corresponding vehicle wires.

   • Use a circuit tester to verify each wire's function before connecting.
   • CAUTION: Test one wire at a time to prevent damage to electronic components.

2. Connect the wires using the provided insulated butt connectors:

   • Strip the ends of each wire and seat them properly in the connector.
   • Use a crimping tool designed for insulated splices to secure the connections.

3. Heat the connectors:

   • Apply heat directly to the center of each splice using a hot air gun.
   • Work from the center outward until the tubing recovers and adhesive flows.
   • Allow the connections to cool before inspecting for integrity.

Step 3: Ground the System

1. Locate a grounding point near the wiring harness, such as the vehicle frame or cross member.
   • Do not drill into the vehicle floor or bed.
2. Clean the area to remove dirt, rust, or undercoating.
3. Drill a 3/32" hole at the grounding point and secure the white wire using the provided eyelet and screw.

Step 4: Verify the Installation

1. Test all connections using a circuit tester or trailer:
   • Verify the functionality of taillights, turn signals, and brake lights.
   • Ensure all connections are complete and secure.
2. If issues are identified, double-check the wiring and connections for errors.

Step 5: Store the 4-Flat Connector

• Store the 4-flat connector in the rear cargo area when not in use to protect it from damage and environmental exposure.

Warnings and Notes:

• WARNING: Overloading a circuit can cause fires. Do not exceed the following limits:
  • Stop/Turn Lights: 7.5 amps (1 per side)
  • Tail Lights: 7.5 amps
• WARNING: Always verify what is behind any surface before drilling to avoid vehicle damage or injury.
• NOTE: Trailer lighting that requires more than 7.5 amps per circuit must use a Trailer Light Power Converter.
• NOTE: If your trailer requires a plug other than the 4-flat, consult your dealer for optional 6-way or 7-way adapters.

Maintenance:

• Inspect the wiring harness periodically for damage, corrosion, or loose connections.
• Reapply heat to connectors if the adhesive seal weakens.

Specifications:

• Maximum Load:
  • Stop/Turn Lights: 7.5 amps (1 per side)
  • Tail Lights: 7.5 amps
• Recommended Grounding Hole Size: 3/32 inches
